3.4.1.1How to configure the drive

Each drive on the SATA interface connects in a point-to-point configuration with the SATA host adapter. There is no master/slave relationship because each drive is considered a master in a point-to-point relationships. If two drives are attached on one SATA host adapter, the host operating system views the two devices as if they were both “masters” on two separate ports. This means both drives behave as if they are Device 0 (master) devices.

SATA drives are designed for easy installation with no jumpers, terminators, or other settings. It is not neces- sary to set any jumpers on this drive for proper operation. The jumper block adjacent to the signal connector is for factory use only.

3.4.1.2How to connect SATA cables

The SATA interface cable consists of four conductors in two differential pairs, plus three ground connections. The cable size may be 30 to 26 AWG with a maximum length of one meter (39.37 inches). See Table 7 for con- nector pin definitions. Either end of the SATA signal cable can be attached to the drive or host.

For direct backplane connection, the drive connectors are inserted directly into the host receptacle. The drive and the host receptacle incorporate features that enable the direct connection to be hot pluggable and blind mateable.

For installations which require cables, you can connect the drive as illustrated in Figure 5.
